Pressure is increasing on Democratic presidential candidate Bernie Sanders to end his campaign, with Democratic Party leaders warning that his continued presence in the race is undermining efforts to beat presumptive GOP nominee Donald Trump.
The new concerns come after Sanders’ recent primary election wins over frontrunner Hillary Clinton in the states of Indiana and West Virginia.
Those victories have provided his supporters with new momentum heading into next week’s primaries in Kentucky and Oregon.
In the 2008 US presidential race, Clinton fought her primary bid against then-US Senator Barack Obama well into June.
Though Clinton has for the past few weeks largely focused her rhetoric on Trump, her aides say the two-front effort hampers her ability to campaign against Sanders and Trump at the same time.
It also means Clinton is spending time in primary states, rather than battlegrounds that will decide the general election.
Sanders’ determination to contest every state remaining has also kept Obama and Vice President Joe Biden largely on the sidelines.
“It all sort of slows the takeoff of her general-election campaign,” said US Senator Sherrod Brown of Ohio, a member of the party’s liberal wing.
However, Sanders has frequently rejected the idea of dropping out, often telling the thousands of supporters who attend his rallies that he still has a narrow path to the presidential nomination.
“Please do not moan to me about Hillary Clinton’s problems,” Sanders said in a recent interview with MSNBC. “It is a steep hill to climb, but we’re going to fight for every last vote.”
A new survey in the US shows a surge in national support for Trump against Clinton. The Reuters/Ipsos poll shows 41 percent of respondents supported Clinton while 40 percent backed Trump, with 19 percent undecided.
The latest online poll of 1,289 people, conducted from Friday to Tuesday, reveals the dramatic turnaround since Trump became the Republican Party's presumptive nominee.
According to an NBC News/SurveyMonkey poll released Tuesday, 47 percent of voters said they were “scared” that Trump has become the presumptive GOP nominee, while 35 percent reported being “scared” if Clinton were to win the Democratic nomination.
